That looks like the vintage format. Did 당신 accidentally click on the link to use that uploading method? 또는 was it a temporary glitch? I've just added an image and the normal method worked fine for me.
As Flicker mentioned, that's definitely the old format. 당신 probably accidentally toggled it somehow. It should go back to the newest one if 당신 leave the image uploading tab and go back to it.
